Upon examining "Deadly Impact" closely, one will probably come to the conclusion that the Italian filmmakers were really trying to pass off this movie as an American production. The cast has two Hollywood stars, the setting of the movie's events is the American southwest, the filming was actually done in the American southwest, and many of the Italians who worked on this movie are credited not with their Italian names but with English names. This attempted deception didn't really bother me - I was more concerned whether the end results would be entertaining. The movie is somewhat slicker than many Italian action movies from this time period - there's plenty of location footage, there are a few okay stunts involving cars, and the climax involving a helicopter chase must have taken considerable time and money to plan and film. There are also a few unintended laughs, like a musical score that often sounds like it belongs in a Terence Hill/Bud Spencer comedy. But aside from little things like that, I found the movie to be a big bore. The police investigation travels at a snail's pace, even though at times there seems to be missing scenes that would have explained a few things. There's absolutely no tension, no excitement at any time in the movie. The only impact this movie makes is a dull thud.
